Radicals

How do radicals affect bond shapes, is it considered another region of electron density?

Yes, Dr. Lavelle mentioned in class that the lone electron is considered as one region of e- density.

The VESPR theory applies to radicals, and they can be counted as electron densities. For example, in CH3 you have 7 total electrons it's going to be a trigonal planar you're going to have the Carbon as the central atom that is bonded to 3 H's and then you have one electron (unpaired lone pair) on the central atom of carbon.

Yes, a radical with a single electron is still considered a domain for the electron geometry.

I thought CH3 would be trigonal pyramidal because of its tetrahedral geometry and 1 LP bonding region but it's trigonal planar.

A radical is considered a region of electron density and affects bond length as other lone electron pairs do.
